In what electronic products are mercury switches generally found?
In general, if a mechanical switch is not visible in these items, a mercury switch is probably being used. The most common place where mercury switches are used is in thermostats (non-electrical). Mercury-containing tilt switches are found in or under the lids of clothes washers and chest freezers. They stop the spin cycle or turn on a light. They are also found in motion-sensitive and position-sensitive safety switches in old clothes irons and space heaters. Float switches are commonly used in sump pumps to turn the equipment on and off when the water is at a certain level. These switch devices are often visible. Mercury switches are also found in many places in automobiles and tractors.
